Can you still buy tickets in advance at the Venue?

I never go through Ticketmaster to buy tickets for the ballroom call the box office and buy over the phone. They mail them directly to you, or will hold for you. Ticketmaster rips you off with charges/fees

Yep. Sure can

Yes

Yes, definitely! Go to the website

I believe so, but it's easier unless u live near, by to get them through ticketmaster...
